This commentary complements Macaulay et al.'s thoughtful and valuable perspective by attending to some additional matters of theoretical, ethical, and practical importance. First, I argue for how consideration of multiple levels of complementarity between processes in mindfulness and nature experience allow more powerful integrations than building on apparent synergies. Second, I outline how an understanding of mindfulness as a practice and training can illuminate relationships between states, traits and values of equal relevance for human health and sustainable transitions. Third, I discuss some caveats and considerations in planning for mindfulness, pointing to insights that researchers and professionals committed to sustainable cities can gain from "McMindfulness " debates and other controversies around meditation before outlining some tentative ideas for how urban environmental design could support mindful living and mindful action.
